I saw a huge group discussion about this, but
it was way too big so I selected and copied a few ones here:
Low electrolytes is also a good excuse for eating fries.
(Potatoes have potassium.)
One of the more noticeable signs of low potassium levels is muscle cramps. (Been there, done that, eat lots of bananas as a result.)
------------
Pickels, Oranges, Blueberries, Olives
OJ has more potassium than bannanas.
It has sugar, but not so much starch.
Grapefruit is also (I think) fairly rich in potassium.
----------
Bananas and dried apricots, great sources of potassium,
are bit high-carb for anything but a treat or an emergency for me.
---------------
Spinach, other dark leafy greens, zucchini, watermelon, strawberries, broccoli, and mushrooms are lower-carb potassium sources but a bit harder to tuck in your pocket.
-------------
Or, Combine the salted nuts with roasted shelled seeds
like pumpkin and sunflower and sesame
-------------
Beans and flax have far more potassium than pumpkin seeds.
How are you for other tree nuts like hazelnut, walnut, pecans,
chestnuts. A good roast mix.
Make yourself a custom trail mix of seeds and nuts and
the few low carb dry fruits like unsweeten cranberries,
blueberries are high potassium only 40calories in a cup of fresh.
----------
Other high potassium stuff is avacados,legumes,kale and other cruiferous(cabbage turnip families) veggies
-----------
So, for potassium:
Tomato products, canned, paste (2650 mg/ measure)
OJ
Beet greens
Beans, white
Dates, deglet noor,
Milk, canned, condensed, sweetened,
Raisins
Potato
Grapefruit
Snacks, trail mix, tropical (993 mg)
...
Dessert topping, semi solid, frozen (1 mg)

Take a heaping quantity of fruit chunks: grapes, melon, peaches, strawberry. Freeze 'em good. Put 'em in an ice chest without any ice, so they thaw a bit. Serve 'em up around 10:30 AM. They're cold, full of water, and full of electrolytesugarsaltpotassium stuff.

An example of flavoring oils for making flavored waters. I keep on contemplating it- even at $80 the savings vs. cases of Propel at Costco could take just a few weeks. (note- I haven't purchased from this company, but the 22 flavors is the largest variety pack I've seen for sale. Has anyone seen more?)
But then again one could go so much further: imagine doughnut water.
Deep fried water. Caramel water. Heath bar water.
Unfortunately no one seems to sell savory flavor packs to the public.
Raisin cinnamon water. Butter Pecan water. Tiramisu water.
Because I think it'd be fun to try some El Bulli style experiments with flavor extracts.
Roasted bell pepper water. Caramelized onion water. Potato chip water. Teriyaki water.
-----------
Tasty variations on the abvove recipe for sekanjabin include: rose, cinnamon, lemon/orange/citrus (handful of candied peel), and rasberry. While they don't have the cooling effects of mint, they're still quite good and give some variety to my gallon containers of syrups.
-----------
Another source of flavors for your drinking water: Da Vinci. They've got a wide range of sugared and sugar free syrups. Here's a link
http://www.davincigourmet.com/. Nothing really savory, but there are some sweet-spicy flavors like cinnamon and gingerbread. One of my favorites is toasted marshmallow syrup in coffee.

I worked for many years hauling hay, and doing construction and demolition, in West Tennessee (near Memphis). In other words, I have lots of experience with how to manage high temperature, high humidity, and strenuous activity at the same time. All the above advice is good. A few more tips:
1)It is much easier to stay properly hydrated if your drinking water is not too cold. It should feel slightly cool, but that’s all—you will drink much more 60 degree water than you will 40 degree water.
2)Before actual heat exhaustion with its accompanying nausea starts, heat is a very effective appetite suppressant. Make sure to eat enough calories. When I was just beginning to haul hay professionally, I lost 10% of my body weight in 2 weeks; I wasn’t hungry, so I didn’t eat much. I was tired all the time, but assumed it was from the activity; then one morning I looked down at my chest and realized that I could see my ribs everywhere on my rib cage.
3)If you need salt fast, put a pinch of salt in your mouth and spread it around with your tongue—don’t swallow it, but get it all over your gums and cheeks and palate. Avoid swallowing--just stir the salty saliva around your mouth; when you must swallow, swallow only a tiny bit at a time (if it causes nausea, you are swallowing too fast.) The oral tissues are very absorptive—that’s why chewing tobacco works.
